+ merge happened, but do not actually make a commit or
+ move the `HEAD`, nor record `$GIT_DIR/MERGE_HEAD` to
+ cause the next `git commit` command to create a merge
+ commit. This allows you to create a single commit on
+ top of the current branch whose effect is the same as
+ merging another branch (or more in case of an octopus).
